• When DIP SWITCH 6 is set to ON, the product will operate in FAIL SECURE mode. In case of a
failure on the Loop Detector, in the loop wire or loss of power, the outputs will indicate no detection
of a vehicle.
• When DIP SWITCH 6 is set to OFF, the product will operate in FAIL SAFE mode. In case of a failure
on the Loop Detector, in the loop wire or loss of power, the outputs will indicate detection of a vehicle.
DIP SWITCH 7 - Output mode for relay 1
This setting determines how relay 1 should indicate a vehicle detection in the loop. The Loop Detector
can generate a single pulse, each time a vehicle enters or leaves the loop (Pulse mode). Alternatively
the output can be keept activate as long as there is a vehicle present inside the loop (Presence mode).
• When DIP SWITCH 7 is set to ON relay 1 operates in Presence mode and output is activated as
long as a vehicle is present inside the loop.
• When DIP SWITCH 7 is set to OFF relay 1 operates in Pulse mode and generates a pulse each time
a vehicle enters or leaves the loop.
Note: DIP switch 8 and 9 will have different functionality depending if product is set to operate in
Pulse or Presence mode on DIP switch 7.
DIP SWITCH 8 - Time setting for relay 1 (only for Pulse mode)
When the Loop Detector is operating in Pulse mode (see DIP switch 7), the pulse length can be changed
with DIP switch 8.
• When DIP SWITCH 8 is set to ON relay 1 creates a pulse with a duration of 0.5 s for each
activation.
• When DIP SWITCH 8 is set to OFF relay 1 creates a pulse with a duration of 0.1 s for each
activation.
DIP SWITCH 9 - Entry or Exit mode for relay 1 (only for Pulse mode)
When the Loop Detector is operating in Pulse mode (see DIP switch 7), the output pulse can be
generated either when a vehicle enters the loop or when a vehicle exits the loop. This is selected by
DIP switch 9.
• When DIP SWITCH 9 is set to ON relay 1 creates a pulse each time a vehicle exits the loop.
• When DIP SWITCH 9 is set to OFF relay 1 creates a pulse each time a vehicle enters the loop.
DIP SWITCH 8 & 9 - Timeout setting for relay 1 (only for Presence mode)
When relay 1 is operated in Presence mode (see DIP switch 7), a timeout can be set to limit maximum
activation time of a single vehicle detection. If timeout is set different from infinite, the output will
automatically deactivate, if a vehicle has been constantly detected for longer time than set by DIP
switch 8 and 9.
